The following are Network Security Agreements (NSAs) entered into with foreign communications infrastructure providers ensuring U.S. government agencies the ability to access communications data when legally requested. The agreements range in date from 1999 to 2011 and involve a rotating group of government agencies including the Federal Bureau of Investigation (FBI), Department of Homeland Security (DHS), Department of Justice (DoJ), Department of Defense (DoD) and sometimes the Department of the Treasury. According to the Washington Post, the agreements require companies to maintain what amounts to an “internal corporate cell of American citizens with government clearances” ensuring that “when U.S. government agencies seek access to the massive amounts of data flowing through their networks, the companies have systems in place to provide it securely.”

The agreements are arranged by date and the government and corporate parties are listed for each agreement. The list is not necessarily complete. If you can find other public examples of Network Security Agreements with any of the companies listed below or others, please let us know.
